How much will the iPhone 7 Pro cost?

I currently own an iPhone 6s Plus.It's my first and only iPhone as I became an apple fan last year so now I'm planning to buy the new one as well-iPhone 7 but I don't want the regular model I want the bigger one and in this case I heard rumors that this year Apple will be releasing a 3rd model of this next 7th generation of iPhone-7 Pro.I wonder how much do you think it'll cost in comparison to a 6s Plus?I live in Germany and I'm well aware that the European pricing is different from the US one so yeah...how much do you guys think it'll cost?
